`Speciiieation forming part of Letters Patent No. 115,393, dated May 30, 1871.

`To allwhom t may concern:

Be it known that I, JOHN VAUGHAN, of

the city, county, and State of New York, have invented a new and Improved Cup for Windin gV Shuttle-Bobbins 5 and I do hereby declare that the following is a full, clear, and

exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of4 this specification. l

-This invention relates to improvements in j the arrangement of thev cups used in winding shuttle-bobbins; and it consists in mounting the said cupsso that they may vibrate on a horizontal axis, the said vibrations being in the plane of the line of the yarn. The object is to allow the cup freedom to bemoved by the thread, and therebyrelieve the friction on the side wall of the slot and greatly lessen the heat, which is very frequently so great as to scorch the yarn, especially when highly colored with metallic substances.

Figure l is a sectional elevation of a cup such as commonly usedin winding shuttlebobbins,and an' `elevation in dotted lines of the winding-spindle, bobbin, traversing threadguide, and the spool of yarn to vbe wound upon the bobbin, all showing the arrangement in the machine forwinding; Fig. 2 is a side view Of the cup and its support, the latter being partly sectioned; and Fig. 3 is a section i through the support on the line m a: of Fig. 2.

Similar letters of reference indicate corresponding parts. A represents a glass or. metallic cup, such as commonly `used in winding-bobbins, having the funnel-shaped vertical hole B and the slot f (l-the latter through the sidesaid cup b eing placed over the bobbin D, as shown, for

guiding'the thread as itis wound on the bobbin, the thread being drawn, by the turning of the bobbin with the spindle E, through the guiding-slot G and vertically-traversing eye F from the spool G, while the spindle moves slowly downward asthe bobbin is made, the same being done in' the ordinary way, begin- `ning at the base, and winding on in the conical form establishedat the beginning of the winding by the form of the base of the bobbin.` Heretofore these cups have been immovably attached to their supports D, which project horizontally from the frame of the machine, to which I consider the great 'heating of the thread, so common, to be mainly due, partly because the friction of the thread, especially of the lumps Or knots, is greater when the cup cannot yield, and partly because of the stagnant state of the air surrounding the cup. Itherefore propose to mount these cups loosely in the supports F', so that they may oscillate aroundthe axis of the said support, whereby they are allowed to move back and forth according to the friction of the thread on them, and in a great measure relieve it from the sudden shocks it encounters when the knots or lumps strikeagainst the walls of the slots C. The stem of the cup A is shouldered and segmentally recessed, as shown in Fig. 3 of drawing. Through the tubular support F', and into the recessed part of the stem of the cup, passes a screw, which thus allows the cup a slight play in the arc of a circle. I have found, in practice, that when mounted in this way they are kept in such rapid vibration` as 'to' agitate the air and induce currents,

which, acting against the said cups, take away the heat to a great extent, so much so that I have no difficulty in winding the most highlycolored threads,which, up to this time, it has been exceedingly difficult, if not impossible, to wind without scorching or greatly damaging them by heat.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The tubular support Ffand set-screw, combined with cup A having the segmentally-re- `cessed arm, applied as and for the purpose specified. The above specification of my invention signed byme this 13th day of September, 1870.
